The Townshend Allegri Reference is a cutting-edge passive preamplifier designed for audiophiles seeking absolute signal purity and transparency. It uses a microprocessor-controlled autotransformer volume control (AVC) and source switch, connecting sources directly to the power amplifier without active components, thus eliminating noise, distortion, and coloration. The unit incorporates Townshend's exclusive Fractal™ cable technology and advanced seismic isolation to minimize vibration interference. It supports multiple inputs including five pairs of gold-plated RCA phono sockets, two pairs of XLRs, and a 3.5mm stereo jack on the front panel. Outputs include two pairs of RCA and one pair of balanced XLRs. The Allegri Reference offers full remote control and a crystal-clear LED display. Its frequency response extends from 8Hz to 80kHz ±0.1dB, with exceptional channel separation better than 110dB and extremely low distortion figures. The passive design ensures no power supply is needed, preserving the original sound dynamics and detail with exceptional instrument separation and a wide soundstage. It is compatible with both solid-state and tube amplifiers, providing perfect impedance matching for optimal performance.
